Analog Devices, Inc. Isolated SiC Gate Driver ADuM4146
The ADuM4146 is a high-voltage isolated gate driver IC for SiC-MOSFETs and IGBTs.
This device uses Analog Devices' iCoupler® technology to achieve high-speed, highly reliable switching control.
- Industry-leading CMT (I common mode transient immunity)
Guaranteed to prevent gate timing errors
- Built-in desaturation detection circuit to protect SiC during high voltage short circuit
・Built-in Miller clamp prevents malfunction when SiC is turned on
・No need for external current buffer + protection circuits
Can be placed close to the gate of the power device
ONSEMICON SiC power module
ON Semiconductor's SiC power modules achieve a normally-off operation by internally cascode-connecting SiC JFETs and Si MOSFETs.
・Low ON resistance due to SiC FET in which SiC JFET and Si MOSFET are internally cascode-connected
・The gate voltage can be simply driven with 0 to 12 V, the same as for Si MOSFETs, and no negative power supply is required.
・The internal body diode is also Si-based, so the VF in the third quadrant is 1.5V and the Qrr is low even at 150℃.
